Subject: [PATCH] btrfs/163: replace sprout instead of seed

Make this test case inline with the kernel patch [1] changes
[1] c6a5d954950c btrfs: fix replace of seed device

So use the sprout device as the replace target instead of the seed device.
This change is compatible with the older kernels.

While at this, this patch also fixes a typo fix as well.
